This paper propose a new frame level rate control algorithm for improving video quality and decreasing quality variation of an entire video sequence in a very low bit rate environment. In the proposed scheme, the allocated bits to a GOP are distributed to each frame properly according to the frame characteristics as well as the buffer status and the channel bandwidth. The H.264 standard uses various coding modes and optimization methods to improve the compression performance, which makes it difficult to control the generated traffic accurately. In this paper, proper prediction models for low bit rate environments are lust proposed, and a target distortion is determined using the models. According to the target distortion, the bit budget is allocated to each frame. It is shown by experimental results that the new algorithm can generate the PSNR performance better than that of the existing rate control algorithm.

This study is to contribute to the policy decision of cosmetic industry through analyzing marketing mix factors which affects customers' buying intention. For this study, marketing mix factors that impact on cosmetic customers purchasing intention were collected and chi-square independence analysis of SPSS and qualitative analysis technology of Kano & Timko were used. Analysis reached one conclusion, which factors were maximizing customers satisfaction, shows the price discount policy and recommendation from family and colleague. Product's effectiveness, usefulness and skin compatibility were rated as an one-dimensional quality as those factors were linearly affected when customers needs were satisfied. However product's containers, package design, colors, brand reputation, low and middle price, distribution channel and advertising medias were investigated as an indifferent quality and they were rated as low satisfaction/dissatisfaction coefficient of Timko. Therefore they do not need to invest to those factors too much budget for attaining customers' buying intention.

The objectives of this study are to explain the performance patterns of health education and related factors in elementary middle, and high schools in Korea. The survey data were collected by questionnaires from June to September in 1998. the number of subjects were 294 school nurses. The SAS-pc program was used for statistical analyses such as percent distribution, a $x^2-test$, a Spearman correlation est., and logistic regression analysis. The major results were as follows: 1. The performance rates of health education by elementary, middle and high schools was higher than before. But the education time was not as sufficient as desired. 2. Planning and practice for health education in elementary and middle schools were high. The preparation of the instruction for health education in elementary school was especially strong. 3. The need survey for health education was low '-' 32~46%. The performance rates of health education increased yearly in elementary school. 4. The reference data were insufficient for health education; In other words, it was difficult for a systematic education. 5. Usually lecture and other methods were used. 10-15% used only the lecture method. 6. The content of heath education was life style in the lower levels of elementary school, Drinking, smoking, drug use etc. were concentrated on in middle and high school. 7. The education evaluation and application was activated in elementary school, otherwise, was low in high school. 8. School nurses and school performance in health education were influenced significatly by planning of health education and the instruction of heath education in elementary school. In the case of planning, the budget was a significant variable; in the case of instruction, the number of school classs was significant. In conclusion, these findings suggest that a developed health education curriculum be performed gearly in order to create a systematic school health education. Also, it is necessary to activate an evaluation to system measure behavioral changes. It is expected that the improvement of school health education be accomplished through the systematic support of schools by government in the physical, economi, and psychological areas.

Terrestrial ecosystem are a strong sink of carbon. Forest ecosystem, one of them, has been expected to play an important role in climate changing process by absorbing atmospheric carbon dioxide. On the other hand, agricultural ecosystem that consists mainly of annual crops is regarded as poor contributor to carbon accumulation, because its production (carbon hydrate) is decomposed into carbon at a short period, which is emitted to the atmosphere. However, it is thought that fruit tree plays a great role in decreasing atmospheric carbon dioxide concentration, same as forest. Net ecosystem exchange of $CO_2$ (NEE) was measured to estimate carbon fixation capacity using an eddy covariance (EC) system method in 2 years from 2005 to 2006 at an apple orchard in Uiseong, Gyeongbuk. Average air temperature values were higher in 2006 than in 2005 during the dormant season, and lower by about $5^{\circ}C$ over the growing season causing visible cold injuries. Accordingly, we investigated long-term exchange of carbon to determine how much difference of carbon fixation capacity was shown between 2006 and 2005 in terms of environmental and plant variables such as NEE, leaf area index (LAI), and Albedo. NEE was $4.8Mg\;C\;ha^{-1}yr^{-1}$ in 2005 and $4.7Mg\;C\;ha^{-1}yr^{-1}$ in 2006, respectively. Low temperature after July in 2006 decreased LAI values faster than those in 2005. Meanwhile, Albedo values were higher after July in 2006 than in 2005. These results show that the low temperature after July in 2006 apparently affected apple growth.

The term "B film" is contrasted to the term "A film" and it has started life since the Great Depression. Film industry had planned the double bills for the audience attraction; double bills means the release of A film and B film. While A's is made to make profits, B's film is made to meet the balance. B film has two features of low budget and low technology. Nevertheless B film has its own style and aesthetics and ironically has made the film more creative and innovative. Historically, it has been related to European and American avant-garde. Robert Florey who is worthy of notice among the early B film makers has adapted and integrated the expressionist and avant-garde styles into the American feature. He also preferred the greater liberty generally afforded "B" directors. Florey has directed Murders in the Rue Morgue and The Florentine Dagger due to the success of his experimental films. Murders in the Rue Morgue shows the style and aesthetics of avant-garde through horror genre and The Florentine Dagger shows the style and aesthetics of avant-garde through thriller genre.

University buildings are energy-guzzling facility that consume more than 10,000TOE within a campus annually. Even the consumption is on an upswing trend. Behind such high consumption are there cheap power rates for education facility, lack of high-efficiency equipment and ever-increasing use of various information equipment. Being keenly aware that greenhouse gas emission increases due to such rise of energy consumption, the present study carried out a case study. In the case study, the study chose the buildings of E university from top 10 universities that consume energy most in Seoul and examined the current status of their energy consumption and greenhouse gas emission. And then it set the reduction target of greenhouse gas by year. Putting aside a middle and long-termed strategy for later endeavor, it first established the 1st year's implementation plan (2014) for energy saving and greenhouse gas reduction with limited budget and according to greenhouse gas reduction target. The plan is specified as follows. Targets for energy saving are mainly divided into two sectors: machine equipment and electric equipment. 7 ideas were proposed. Three ideas to improve machine equipment are to replace with high-efficiency boilers and chillers and to adjust the position of the cooling tower. By doing so, it was estimated that energy could be saved by 176.34TOE in total and greenhouse gas could be reduced by 370.771t$CO_2$-eq. Four ideas to improve electric equipment include the replacement with LED lights, LED emergency lights and high-efficiency motors and the installation of motion sensors. It was calculated that such replacement could conserve 1,076.08TOE (electric energy) and reduce 2,181.420t$CO_2$-eq (greenhouse gas).

In this paper, the UWB(Ultra-Wide Band) modules such as a pulse generator and the LNA(Low-Noise Amplifier) with AGC(Auto Gain Control) are designed to construct a cross-borehole pulse radar system, of which performance is compared with the existing system. The budget and specification of the radar system are determined by calculating the total path loss of the underground medium including an empty cavity. The pulse generator is fabricated to have the repeatation frequency 40 kHz, the pulse width lower than 5 ns and the peak signal level +73 dBm. The UWB LNA is designed to have the noise figure 3.77 dB, the variable gain range 100 dB and the frequency range of 20 MHz to 200 MHz. Compared with the existing system in an actual test site, the implemented system renders it possible to detect the blind area due to the UWB LNA with low noise figure.

Background: The overall cervical cancer incidence rate is low in Iran; however, because of a higher risk of death for cervical cancer, a disease that kills women in middle age, a cervical cancer control program is needed. The aim of this study was to provide consensus recommendation for cervical cancer prevention in Iran and other Muslim societies with low incidences of cervical cancer. Materials and Methods: Through a practical guideline development cycle, we developed six questions that were relevant to produce the recommendation. We reviewed 190 full text records of cervical cancer in Iran (1971 to 2013) of which 13 articles were related to the data needed to answer the recommendation questions. We also reviewed World Health Organization, IARC, GLOBOCAN report, Iran Ministry of Health cancer registry report and 8 available foreign countries guidelines. Lastly, we also evaluated the Pap smear results of 825 women who participated in the Iranian HPV survey, of whom 328 were followed-up after a 5-year interval. Results: The obtained data highlighted the burden of HPV and cervical cancer situation in Iran. Experts emphasized the necessity of a cervical cancer screening program for Iranian women, and recommended an organized screening program with a cytological evaluation (Pap smear) that would start at the age of 30 years, repeated every 5 years, and end at the age of 69 years. Meanwhile, there is no need for screening among women with a hysterectomy, and screening should be postponed to post-partum among pregnant women. Conclusions: An organized cervical cancer screening is a necessity for Iran as more than 500-900 women in middle age diagnosed with an invasive cervical cancer every year cannot be ignored. This recommendation should be taken into account by the National Health System of Iran and Muslim countries with shared culture and behavior patterns. CUBA HPV test could be consideration in countries Muslim country with appropriate budget, resources and facility.

This study was conducted to develop expanding strategies of nutrition counseling in school foodservices. The study participants were 102 school dietitians in Gyeonggi province, and information on the current status, dietitians' necessity awareness, and practical activation needs for nutrition counseling were investigated. While 78.8% of dietitians were aware that nutrition counseling was in need, it was only 31.3% who understood the necessity of nutrition counseling. The implementation rate of students' nutrition counseling was 26.2%, and 74.0% of counseling dietitians reported that they conducted nutrition counseling because it was on the inspection list by the Office of Education. Overall, dietitians did not have high consciousness of the need for nutrition counseling. The implementation rate of students' nutrition counseling was remarkably low due to the reason of excessive work and insufficient participants, and it was interpreted that dietitians had a low intrinsic motivation for nutrition counseling. So, we suggested several strategies to activate school nutrition counseling as follows. First of all, dietitians needed to increase the students' participation rate by promoting the importance of nutrition counseling to students and by assigning their available work hours for nutrition counseling. Second, in academic communities, standardized counseling manuals and media covering the important nutrition and health issues should be developed and disseminated, and education programs needed to build up dietitians' self-esteem and knowledge on nutrition counseling. Lastly, the Office of Education should have the initiative in activating nutrition counseling in school foodservices by supporting a budget and counseling dietitians who exclusively responsible part-time counseling at schools.

In Korea, co-utilization of research equipments has been low, even though co-utilization policies for them have been implemented for a long time. This situation results because the policy formation and implementation for the co-utilization of research equipments have been conducted from the perspectives of the policy maker not from those of the researchers and equipment managers. Therefore, this work has been conducted for analyzing the current state of co-utilization of research equipments as well as for discussing the future developments of its more co-utilization in the basic research programs by adopting the bottom approach in policy implementation theory. The research shows that firstly principal investigators, especially professors in universities, have placed a relatively low priority on the co-utilization of research equipments, secondly implementation resources such as high quality technicians and affordable budget for co-utilization are scare, thirdly incentives for the activation of co-utilization in the stage of daily operation of research equipments are lacking. As a result, the study tries to develop a more economic means and information tools for the promotion of co-utilization of research equipments in the perspectives of bottom-up approach in policy implementation theory.
